2. Description of the Related Art A car stop which prevents the vehicle from entering by raising and lowering a lifting pole and making it possible by immersion and lowering has been proposed, for example, in Japanese Patent Application No. 5-248725 of the present applicant.

According to this, a lifting pole housed in an embedding case for underground installation is provided with a plurality of bollards which can be raised and lowered by means of raising and lowering means interposed therebetween, for example, a plurality of bollards. A plurality of interlocking electric bollards are provided which include a motor-driven operating means that operates simultaneously with the elevating means of the bollards.

The raising and lowering means is for rotating one of the chain sprockets by, for example, a pair of upper and lower chain sprockets and a rotating chain wound around these and connected to a lifting pole, or a winding shaft and the winding shaft. A winding wire that can be wound on a shaft and that is connected to a lifting pole and that uses a rotating force such as a rotating shaft of the winding shaft. The operating means is, for example, a motor-driven rotating chain or geared wire. (Drive wire) and a chain sprocket that is installed at the tip of a rotating shaft that protrudes outward from the embedding case for transmitting the rotational force of the chain sprocket, winding shaft, etc., and meshes with the rotating chain or geared wire. And the gears are used to operate the lifting / lowering means in a simultaneous interlocking manner.

[0005]

In order to put such a plurality of interlocked electric bollards into practical use, for example, the operating means is, in particular, a combination of a geared wire and a gear, among the above-mentioned installation and maintenance. It is simple and convenient.

[0006] That is, the geared wire is made of a series of wires and reciprocates in both directions, and is flexible to some extent. Therefore, the wire itself is installed outside the embedding case for underground installation, while it is installed above the ground. It is easy to arrange it so that it is bent upward with respect to the motor side to be installed, and since it is a series, it can be attached and detached at the time of installation and maintenance by inserting and pulling it into the protective pipe Because it is.

[0007] However, when the actuation means using the geared wire and the gear gear is used, there is a disadvantage that the gear teeth of the geared wire are relatively easily lost. That is, since the geared wire is formed by spirally winding gear teeth around the outer periphery of the wire, if there is a factor that hinders the rotation on the gear gear side, for example, the gear teeth of the geared wire have excessively large gear teeth. This is because a load is applied. Particularly, when the lifting / lowering means of the plurality of vehicle stop units are operated or when the operation of the lifting / lowering means is not performed smoothly in one of the vehicle stop units, this operation is performed. The possibility of missing gear teeth increases.
